Here's a boredom experiment I'm working on. I found these 2 lamps years back, 
and then again over the years but always .max; till recently I found I think at 
archive3d, a .3ds version I converted. 
Although made by the same artist they are remarkably inconsistent in that some 
of the sphere parts were walls and others like the sphere object in TG. So I 
took them to my pal's office and split the spheres up and deleted the inside 
ones where they appeared, saved it to my stick and at home loaded it in 
PoseRay and was able to get all the spheres back into one object, U/V mapped 
them in PoseRay and here we are.
If anyone wants to play with these I'll pack 'em up with the .tgc I use for the 
Glass and necessary maps(2 or 3). Glass colour is set in the tranparency slider.
The assembled lo res images attached are labeled for clarity...I noticed that 
with soft shadows the transpaent colour from the glass shader projects, but not 
really with no SShadows.
In the 2 lamps pic they both share the identical settings including lght fall off.
